I should have provided the page number and section details - sorry about that.In the newest version of the STEP guide, page 12 Section 1.B.2 it states the following: So, my question was dealing strictly with whether or not I *need* to be at 50 fps in all areas in order to even begin modding my game with core mods. In other words, I'm ready to say to myself, "I see no performance issues and my game seems very stable. My FPS is running around 40-50fps in most areas, but drops to 25 in very demanding areas. I consider this stable and will proceed from here." But STEP is telling me I shouldn't proceed unless I am at 50fps in all areas. I know systems are vastly different and some people even with beefy boxes can't get consistent fps in certain places, so I wondered what those of us with mid-range machines should do here. I'm probably gonna call it "good enough" where I'm at, but I am interested to hear more. Thanks.
